Each floor stop operation forcibly stops each floor in response to a car call (If you enter the car from the first floor and register a car call on the 10th floor, it will also stop on the 2nd to 9th floors where no call is registered. ) To shorten the time in which the cage is closed. This operation is mainly controlled by time and is often selected only at night. In addition, for security alarm operation, there is a push button for the security alarm device in the car, and if the user feels danger and presses the push button, the car call will be stopped at each floor and the car will be closed. prevent. A third party is notified by ringing a dedicated buzzer installed at the hall at the same time as stopping on each floor. Stopping operation at each floor and ringing of the buzzer are canceled by a third party operation. Also, in the crime prevention operation, there is a push button for crime prevention operation at the reference floor, and when the push button is pressed, a car call that does not respond to the hall call can be registered to prevent passengers from entering from other floors.
In addition, as a prior art, there is known an elevator crime prevention operation device that detects the occurrence of an abnormality in the car due to the car call registration state, the load fluctuation in the car, and controls the operation such as stopping the nearest floor and sounding the announcement. (For example, refer to Patent Document 1).

次に、図２によりエレベータの防犯運転装置の動作フロー説明する。
図２において、ステップＳ１でエレベータかご１内の防犯カメラ２から外部記録装置３の画像処理基板４に画像が入力され、ステップＳ２で画像処理基板４による画像処理が行われる。ステップＳ３で画像処理基板３により暴れ度合いを定量化して暴れを検出する。暴れを検出したらステップＳ４で通信装置５に暴れ度合いの検出結果を送信し、ステップＳ５で外部記録装置へ高密度記録を要求する。次に、ステップＳ６〜Ｓ８で暴れ度合いの強さを、大、中、小の３段階で判断する。暴れ度合いの強さが大の場合は、ステップＳ９のエレベータへアナウンス要求、ステップＳ１０のエレベータへ暴れ運転大を要求、ステップＳ１１の発報設定有無、ステップＳ１２の保守会社監視センター７へ発報を行う。また、暴れ度合いの強さが中の場合は、ステップＳ１３のエレベータへアナウンス要求、ステップＳ１４のエレベータへ暴れ運転中を要求、ステップＳ１５の発報設定有無、ステップＳ１６の保守会社監視センター７へ発報を行う。また、暴れ度合いの強さが小の場合は、ステップＳ１７のエレベータへアナウンス要求、ステップＳ１８の発報設定有無、ステップＳ１９の保守会社監視センター７へ発報を行う。 Next, the operation flow of the elevator crime prevention operation apparatus will be described with reference to FIG.
In FIG. 2, an image is input to the image processing board 4 of the external recording device 3 from the security camera 2 in the elevator car 1 in step S1, and image processing by the image processing board 4 is performed in step S2. In step S3, the degree of rampage is quantified by the image processing substrate 3 to detect rampage. When the rampage is detected, the detection result of the rampage degree is transmitted to the communication device 5 in step S4, and high density recording is requested to the external recording device in step S5. Next, in steps S6 to S8, the strength of the rampage degree is determined in three stages of large, medium, and small. When the intensity of the rampage is large, an announcement request is sent to the elevator in step S9, an rampage driving magnitude is requested to the elevator in step S10, an alarm is set in step S11, and an alert is issued to the maintenance company monitoring center 7 in step S12. Do. If the level of rampage is medium, an announcement request is sent to the elevator in step S13, a rampage operation is requested to the elevator in step S14, the alarm is set in step S15, and the maintenance company monitoring center 7 in step S16 is issued. Give information. If the intensity of the rampage is small, an announcement request is sent to the elevator in step S17, a notification is set in step S18, and a notification is sent to the maintenance company monitoring center 7 in step S19.

次に、図３によりエレベータ側の動作フロー説明する。
図３において、ステップＳ２１でエレベータへの暴れ運転要求が有ると、ステップＳ２２でエレベータの暴れ運転が可能かどうか判断される。暴れ運転が可能な場合、ステップＳ２３で暴れ運転大が要求されているかを判断する。ステップＳ２３で暴れ運転大が要求されている場合は、ステップＳ２４で防犯警報装置動作指令を自動的に出力する。ステップＳ２３で暴れ運転中が要求されている場合は、ステップＳ２５でかご走行中かどうかを判断し、走行中であればステップＳ２６で最寄階停止指令を出力する。 Next, the operation flow on the elevator side will be described with reference to FIG.
In FIG. 3, when there is a rampage operation request to the elevator in step S21, it is determined in step S22 whether the rampage operation of the elevator is possible. If the rampage is possible, it is determined in step S23 whether the rampage is requested. If a large runaway is requested in step S23, a security alarm device operation command is automatically output in step S24. If it is requested in step S23 that the rampage is being performed, it is determined whether or not the car is traveling in step S25. If the car is traveling, a nearest floor stop command is output in step S26.

上記外部記録装置３内の画像処理基板４における暴れ度合いを定量化して暴れを検出する装置は、例えば図４に示すように構成されている。
すなわち、防犯カメラ２で撮影した画像を動き算出部３１に出力する。動き算出部３１は防犯カメラ２で撮影された撮影時刻が所定時間異なる２枚の画像から画像内の各点の動きの向き及び大きさを算出し、各点の動きの向き及び大きさから乗客の動きの向き又は大きさのうちの少なくとも一方の乗客の動きのばらつき量を算出する動き算出手段である。撮影時刻が所定時間異なる２枚の画像は、連続して撮影した前後２枚の画像となる。例えば、ビデオカメラを用いてＮＴＳＣ方式で撮影した場合、撮影は１／３０秒毎に行われる。この場合、所定時間異なる２枚の画像としては、連続した２枚の画像とすることもできるが、途中の画像を間引いたり、撮影間隔を変えたりすることで、１／１０秒毎にしたり、１秒毎にしたりすることができる。また、動き算出部３１は記憶領域を備えており、受け取った画像を適宜保存することができる。動き算出部３１で算出された乗客の動きのばらつき量は補正部３２に出力される。かご１内は閉空間であり、扉開閉判定部３３は閉空間であるかご１の内外に通じる扉の開閉状態を判定する扉開閉判定手段である。扉開閉判定部３３は防犯カメラ２によって撮影された画像から扉の開閉状態を判定し、動き算出部３１及び補正部３２にその結果を出力する。なお、動き算出部３１は、かご１内への乗客の入退場データを除いて乗客の動きのばらつき量を算出する。補正部３２は、扉開閉状態毎に分類された乗客の動きのばらつき量の平均値及び分散値のデータベースから構成される統計モデルに基づき、暴れ判定手段で用いる乗客の動きのばらつき量又は乗客の暴れ判定閾値を補正する補正手段である。補正部３２は、統計モデルデータベース３４に記憶されている統計モデルを用いて乗客の動きのばらつき量を補正し、その結果を暴れ判定部３５に出力する。暴れ判定部３５は、乗客の動きのばらつき量と乗客の暴れ判定閾値とを比較して乗客の暴れを判定する暴れ判定手段である。暴れ判定部３５は、補正された乗客の動きのばらつき量に対し、閾値処理を施して、乗客の暴れの有無を判定する。統計モデルを構成するデータベースの内容については、閉空間の種類毎に分類された乗客の動きのばらつき量の平均値及び分散値でもよい。閉空間の種類としては、壁がガラス張りである場合、壁に窓が付いている場合、壁の色が違う場合、模様が違う場合などがある。また、データベースの内容については、防犯カメラ２のアングル毎に分類された乗客の動きのばらつき量の平均値及び分散値のデータベースでもよい。このようなデータベースから構成される統計モデルに基づき、補正部３２で乗客の動きのばらつき量又は乗客の暴れ判定閾値を補正し、暴れ判定部３５に出力する。 An apparatus for quantifying the degree of rampage in the image processing substrate 4 in the external recording apparatus 3 and detecting the rampage is configured, for example, as shown in FIG.
That is, an image captured by the security camera 2 is output to the motion calculation unit 31. The motion calculation unit 31 calculates the direction and magnitude of movement of each point in the image from two images taken by the security camera 2 with different shooting times for a predetermined time, and the passenger is calculated from the direction and magnitude of the movement of each point. It is a movement calculation means which calculates the variation amount of the movement of at least one passenger among the direction or magnitude of the movement. The two images having different shooting times for a predetermined time are the two images before and after consecutive shooting. For example, when a video camera is used to capture an image using the NTSC system, the image is captured every 1/30 seconds. In this case, the two images that are different for a predetermined time can be two consecutive images, but by thinning out the middle image or changing the shooting interval, it can be set every 1/10 seconds, Or every second. In addition, the motion calculation unit 31 includes a storage area and can appropriately store the received image. The variation amount of the passenger motion calculated by the motion calculation unit 31 is output to the correction unit 32. The inside of the car 1 is a closed space, and the door open / close determining unit 33 is a door open / close determining unit that determines the open / closed state of the door that communicates with the inside and outside of the car 1 in the closed space. The door open / close determining unit 33 determines the door open / closed state from the image taken by the security camera 2 and outputs the result to the motion calculating unit 31 and the correcting unit 32. The motion calculation unit 31 calculates the amount of variation in passenger movement, excluding passenger entry / exit data into the car 1. The correction unit 32 is based on a statistical model composed of a database of average values and variance values of passenger movements classified for each door open / closed state, and the passenger movement fluctuations used by the rampage determination means or the passenger movements. It is a correction means for correcting the rampage determination threshold. The correction unit 32 corrects the amount of variation in passenger movement using the statistical model stored in the statistical model database 34 and outputs the result to the rampage determination unit 35. The rampage determination unit 35 is rampage determination means for comparing the amount of variation in passenger movement with the passenger rampage determination threshold value to determine passenger rampage. The rampage determination unit 35 performs threshold processing on the corrected variation in the movement of the passenger to determine whether the passenger is rampant. About the content of the database which comprises a statistical model, the average value and dispersion value of the variation amount of the movement of the passenger classified for every kind of closed space may be sufficient. The types of closed space include a case where the wall is glazed, a window is attached to the wall, the color of the wall is different, and the pattern is different. Moreover, about the content of the database, the database of the average value and dispersion | variation value of the variation amount of the movement of the passenger classified for every angle of the security camera 2 may be sufficient. Based on the statistical model configured from such a database, the correction unit 32 corrects the variation amount of the passenger movement or the passenger rampage determination threshold value and outputs the corrected value to the ramp determination unit 35.

図５は暴れを検出する装置の動作を示すフローチャートである。ステップＳ３１で防犯カメラ２により画像が撮影され、画像が入力される。ステップＳ３２で扉開閉判定部３３はとびらの開閉状態を判定する。次に、ステップＳ３３で動き算出部３１は撮影時刻が所定時間異なる２枚の画像からオプティカルフローを算出する。このオプティカルフローは、画像の各点における動きの向きと動きの大きさを表わした見掛けの速度分布である。このように、暴れ動作と相関のある乗客の動作のばらつき量に着目し、ばらつきが大きい場合に暴れありと判断しているため、ばらつきの小さい通常の乗客の動作等は誤判定されず、安定した暴れ検出が実現できる。続いて、ステップＳ３４で動き算出部３１はオプティカルフローから乗客の動きのばらつき量を算出する。乗客の動きのばらつき量は、例えば、乗客の動きの向きのばらつき又は乗客の動きの大きさのばらつきであり、画像の各点で求められた動きの向き、動きの大きさの分散値又は標準偏差として求められる。更に、ステップＳ３５で補正部３２は統計モデルデータベース３４に記憶されている統計モデルを用いて乗客の動きのばらつき量を補正し、防犯カメラ２の設置条件、環境への依存度を軽減した値に修正する。統計モデルは、監視エリア（かご内）毎、扉の開閉状態毎に予め用意しておく。例えば、防犯カメラ２の設置後に、通常の乗客の動作に対して、乗客の動きのばらつき量を試験的に算出し、その時間的な平均値Ｍと分散値σとを統計モデルとして記憶する。ステップＳ３４で算出した乗客の動きのばらつき量をＶとすると、ステップＳ３５では補正値Ｖ´を式（１）から算出する。
Ｖ´＝（Ｖ−Ｍ）÷σ （１）
最後に、ステップＳ３６で暴れ判定部３５は補正値Ｖ´を閾値処理し、乗客の暴れの有無を判定する。ここでは、補正値Ｖ´が閾値以上である場合に暴れ有りと判断する。以上のステップＳ３１〜Ｓ３６までの処理が所定の時間間隔で繰り返し実行される。 FIG. 5 is a flowchart showing the operation of the apparatus for detecting a rampage. In step S31, an image is taken by the security camera 2, and the image is input. In step S32, the door open / close determining unit 33 determines the door open / closed state. Next, in step S33, the motion calculation unit 31 calculates an optical flow from two images whose shooting times are different by a predetermined time. This optical flow is an apparent velocity distribution representing the direction and magnitude of movement at each point of the image. In this way, paying attention to the amount of variation in passenger movement that correlates with rampage movement, it is determined that there is rampage when the variation is large. Can be detected. Subsequently, in step S34, the motion calculation unit 31 calculates the amount of variation in passenger movement from the optical flow. The amount of variation in the movement of the passenger is, for example, variation in the direction of movement of the passenger or variation in the size of the movement of the passenger, and the direction of movement obtained at each point of the image, the variance value of the size of movement, or the standard Calculated as deviation. In step S35, the correction unit 32 corrects the amount of variation in passenger movement using the statistical model stored in the statistical model database 34, and reduces the dependence on the installation conditions and environment of the security camera 2 to a value. Correct it. A statistical model is prepared in advance for each monitoring area (inside the car) and each door open / closed state. For example, after the installation of the security camera 2, the amount of variation in passenger movement is calculated on a trial basis with respect to normal passenger movement, and the temporal average value M and variance value σ are stored as a statistical model. When the variation amount of the passenger movement calculated in step S34 is V, a correction value V ′ is calculated from equation (1) in step S35.
V ′ = (VM) ÷ σ (1)
Finally, in step S <b> 36, the rampage determination unit 35 performs threshold processing on the correction value V ′ to determine whether the passenger is rampant. Here, it is determined that there is a rampage when the correction value V ′ is equal to or greater than the threshold value. The above steps S31 to S36 are repeatedly executed at predetermined time intervals.
